@ RanieHBS I actually like the witch idea. I'll tie that in somehow. But anyway, another hint: In case you don't know already, Annabeth is an original creature/thing whatever, but she's also THE creature, THE monster, THE legend etc. I'm updating again now. I want some more ideas by the time I'm done ;)
@ TheRockshowChick You're half there. Annabeth's daughter is a small part of the secret, there's more to Elizabeth that Angelo will ever realize or understand. It's kind of like her daughter is the tip of the iceberg, if you know what I mean. I won't give too much away, but here's a little hint: there is a reason why Annabeth likes to dress in Steampunk/Victorianesque clothes and prefers old fashioned names ;) Happy guessing!
I really like this, so the big secret is that Annabeth has a daughter? That doesn't seem like a BIG secret to me.... I first thought she was some kind of creature of the night but I guess I was wrong. Update soon :D
